This rocket is similar in shape, size, and weight to the high-explosive type. However, it is provided with only a propellent charge, the head being inert. No fuze is provided. The end of the stabilizer tube is extended to counter-weight the head and make the ballistics of this rocket similar to that of the H.E. type. A safety pin passes through the stabilizer tube at the upper end and in order to make the detail of firing this rocket similar to that necessary in the above HE type. Since there is no fuze, it naturally serves no useful function. In all other respects the rocket is similar to the HE type. It is used for target practice only.
